Answer: The first one (12+17)-9=(23-7)+4

Explanation: First add 12 and 17 because it’s in parentheses which will give you 29. Then subtract 9 to get 20. After that, solve the problem on the right side of the equal sign, therefore 23-7 is 16. Lastly, add the 4 to 16 to get 20 which means that this equation is equal because (12+17)-9 does give you the same answer as (23-7)+4 which in conclusion means it’s a true equation.

7/10 - 1/2 whats the answer
Serjik [45]
To find the answer, we can use expansion to turn the fraction’s denominator to be the same:

1/2
= 1×5 / 2×5
=5/10

We can then proceed to find the answer:

7/10 - 5/10
= 2/10
= 1/5

Therefore the answer is 1/5.

Hope it helps!

A salad bar offers vegetable platters in 4 sizes (small, medium, large, and super-sized) and 6 different vegetables to choose fr
quester [9]

Answer: She could create 60 platters.

Step-by-step explanation:

Given: A salad bar offers vegetable platters in 4 sizes (small, medium, large, and super-sized) and 6 different vegetables to choose from.

Number of combinations of selecting <em>r</em> things from <em>n</em> things is given by:-

^nC_r=\dfrac{n!}{r!(n-r)!}

So, the number of combinations of selecting 2 different vegetables from 6 = ^6C_2=\dfrac{6!}{2!4!}=\dfrac{6\times5}{2}=15

Now, By Fundamental counting principle, the number of different platters she could create = (number of ways of selecting 2 different vegetables from 6) x (Number of sizes)

= 15 x 4

= 60

Hence, she could create 60 platters.
